T all whom it may concern:

Be it known, that we, FERDINAND F. W AEOHTER and WILLIAM S. CAMPBELL, c1t1- adelphia, Pennsylvania, have invented certain Improvements in Pier Structures, of which the following is a specification.

Our invention relates to certain improvements in pier structures for loading vessels,

either with cargo or withbunker coal.

One object of our invention is to reduce the cost of a structure of this type arid. to provide a movable hopper structure from .which the coal is discharged, and to mount on the pier an overhead crane structure for carrying the telescopic chute, when such a chute is employed.

A further object of the invention is to design the crane structure so that cars, or other conveying mechanism, can be manipulated in the space under the span of the crane structure.

In the accompanying drawingsi Fig. l is a transverse sectional view of a pier illustrating our invention. On one side of the pier is a vessel being loaded with cargo coal and on the other side is a vessel being loaded with bunker coal; Fig. 2 is a longitudinal sectional view of a portion of the pier structure; r Fig. 3 is a diagrammatic plan view of a pier, showing the tracks; and

F1gs.-4 and 5 are detail views of the chute. Referring to the drawings, 1 is a pier on which is mounted a series of, structural frame 2 spaced a given distance apart and carrying an openwork structure}, which extends substantially the full length of the pier. The structure consists, in the present instance, of a central frame 4, suitably braced, a base frame 5, and a heavier girder frame 6 carried by the central frame 4 and overhanging the central frame. On the girder frame .6 are rails 7 spaced a considerable distance apart and arranged to travel on the rails is a crane structure 8 in the form of an Open span. @n the girder frame 6, in the present instance, are three tracks. The two outer tracks 9 are the tracks for the loaded cars and the central track 9 is the return track for the empty carsa At the outer end of the pier, the tracks-9 merge ture.

into the track 9*. At the land end of the pier the track 9 merges into the tracks 9.

40 are elevators for raising the cars from the tracks 41 to the level of the pier struc- 42 are car dumping tracks for discharging the cars into the specially constructed pier cars.

The above description relates to one arrangement of tracks, but the arrangement can be modified without departing from the main feature of the invention. Other means may be used for conveying material 'to the pier, if desired.

Thev crane structure'is arranged to travel the full length of the pier. Mounted on the base of this structure -8 is a turn table 10, carrying a frame 11, which supports a boom 12, and the power house 13, in which is located the mechanism which operates the boom and raises and lowers the telescopic chute which is suspended from the I boom.

At each side of the base frame 5, in the present instance, are hopper structures 16 mounted On' trolleys .15 .havingwheels adapted to rails 14 on the frame 5. At the upper end of each hopper structure is an I extension 43, which passes between guide wheels 44 on the frame 6. 17 are hoppers, which are located in the upper portion of the hopper structure and are arranged to receive material through chutes 18 mounted 0n the frame 6. These chutes are arranged directly under the rails 9 for the cars guides 25 on t e chute 20. The shaft of the motor is 'conne ed to the shaft on which is a worm 26,-,Wl1i0l1 is geared to the worm wheels 27 on shafts 28 adapted to bearings on the extension chute 22. On the lower shaft are pinions 29, which gear with racks and can be raised and lowered by the I the extension chute will be projected, and,

when the movements-is reversed, it will be retracted.

The outer end of'the chute is suspended by ropes-33, which pass around sheaves to a drum 34, which may be turned by hand, or power, as desired. The chute 25, with its extension 22, discharges material into a hand the telescopic chute can be raised and collapsed so that it can assume the position telescopic chute 35, which is suspended byropes 36 from the boom 12.; Thechute is manipulated by power apparatus in the powerhouse 13 carried by thestructure 8 shown by dotted lines in Fig. 1, clear of a vessel, toallow the'crane to be moved to either-side of the. pier, and can be lowered into a vessel, or extended, as shown in full .lines.

When it'is desired, the inclined chute 20 can discharge material directly into the hold of a vessel without using the telescopic chute, asshown at the right of Fig. 1. When the telescopic. chute is raised, the boom can be moved so as to be directly above the pier, which will allow a vessel to be brought to either side of the --pier without the boom interfering with the-rigging.

The means for operating the telescopic chute forms no part of the present inven-' -t1on, as it is setforth and claimed in an aplication for pateht filed by William S. ampbell on the eighth day of February, 1921, Serial N 0. 443,386.

By the above construction, it will-be seen that a vessel can be loaded at either side of a pier and that the hopper structures can be-moved into alignment with the hold of a vessel. When a telescopic chute is to be used, then the crane structure is traversed to a point so that the boom will be above the hold of a vessel andthe telescopic'chute can be lowered into the hold, after which the chute of the hop er structure is ad'usted so as to feed material to'the upper e d of the'chut'e. p

B running loaded cars over one of the trac s 9, the. cars can be discharged directly into the hopper and the material will flow down the inclined chute and into the telescopic chute from which it is discharged by any suitable discharge mechanism at the base.

. The cars, when unloaded, are run out to of the crane and arranged to receive'materialfjfrom the hopper chute, the crane being pivoted so that the boom of the crane "and the telescopic chute can be moved directly above the pier.

2.*The combination of a pier structure having longitudinal rails at, each side; a hopper structure mounted on the rails at each side of the pier structure and arranged to be moved longitudinally thereon; a hop- .per and chute on each hopper structure; a series of tracks on the pier structure; cars arranged to travel on said tracks; a rail at each side of the pier structure; a crane structure; arranged to travel onthe rails, said crane structure be1ng .1n the form of an, open span; a pivoted boom on said crane structure and. a'telescopic chute suspended from the boom and arrangedto be moved to either side'lof the pier structure, or to be located directly above the'pier structure.
